you, a demon, and your brother arrived at the Hashira Headquarters, where your brother was knocked out. You stayed in a box your brother carried on his back, to hide you from sunlight. And you woke up to being thrown around, and stabbed by a katana.

you climbed out the box, seeing the Wind Hashira, Sanemi. He was holding his arm out, his wrist sliced. Blood was dripping onto the floor, and Sanemi wanted to prove you weren't innocent, and you would eat him. So he taunted you with his blood.
